Product Positioning

The 3RV2431-4PA10 is a transformer protection circuit breaker in the S2 size of the Siemens SIRIUS 3RV2 series. With a high short-circuit trip value and adjustable thermal overload protection, it is suitable for applications that can withstand transformer inrush currents.

Core Product Advantages and Features
Dedicated design for transformer protection
The N-operation short-circuit trip value is fixed at 820A, which is higher than the rated value of the A-operation compared to general motor protection circuit breakers. It can withstand transformer excitation surges without tripping.
Adjustable thermal overload protection
The A-operation (overload) scale can be adjusted within the range of 28...36A, allowing for easy fine-tuning of the protection current according to the actual transformer capacity.
S2 size high blocking capacity
With a rated insulation voltage of 690V and a breaking capacity of 65kA in a 400V system, it meets the short-circuit protection requirements of most low-voltage switchboards.
Standardized installation and expansion
It uses screw terminal connections, can be snapped onto a 35mm DIN rail, and can be equipped with auxiliary contact modules for status feedback.
